Emergency discussion: Principia on Reddit

First of all, I am sorry about my absence for this three months. I am currently in university majoring electric engineering so I don't have many time playing Principia.

Second, and the most important thing: I suggest having a subreddit of Principia so we can keep in touch even after the server having problems or something like that, because we really don't know when will it happens.
